Background and Objectives Vocal polyp is one of the most common benign diseases of vocal fold caused by overuse of voice. Laryngeal microsurgery is the first treatment of choice for vocal polyp. However, surgery has many risks such as side effects of general anesthesia, injury of tooth and psychological burden. And we often experience reduction of vocal polyps without surgical procedure. The purpose of study is to evaluate the effect of non-surgical treatment such as vocal hygiene education and proton pump inhibitor (PPI) in patients with vocal polyp. Materials and Method We performed retrospective study for seventy-three patients of vocal polyp who treated with non-surgical modalities such as vocal hygiene education and PPI over three months. Treatment outcomes and risk factors such as age, sex, polyp size, position, symptom duration, presence of laryngopharyngeal reflux (LPR) symptoms, smoking history, voice abuse history and vocal hygiene education were evaluated by comparison between polyp size improved group and non-improved group. Results 5.5% of enrolled patients showed complete response and 23.3% showed partial response without surgery. Polyp size improved group significantly carried out more practice of vocal hygiene education treatment than the non-improved group (p=0.040). And the presence of LPR symptoms [hazard ratio (HR) 3.368, confidence interval (CI) 1.055-10.754, p=0.040] and not performing of vocal hygiene education (HR 3.664, 95% CI 1.078-12.468, p=0.038). Conclusion Vocal hygiene education can be a useful treatment option when making a decision to treat with vocal polyp.
